State of Minnesota, have invented certainv new and useful Improvements in Portable lVhcel-'lfracks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to improvements in portable wheel tracks for dredges, ditching machines, excavators and the like; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the Vseveral views.

Referring to the drawings, Figure 1 is a fragmentary view in side elevation of a ditching machineresting on a pair of the improved wheel tracks, only one of which is shown; Fig. 2 is a plan view of one of the improved wheel tracks, some parts being broken away; Fig. 3 is a longitudinal central section taken on the line :r3- w3 of Fig. 2; and Fig. 4 is a transverse section taken on the line aat-co4 of Fig. 3.

The numeral 1 indicates a plurality (as shown four) of longitudinal timbers placed side by side to form the bottom of a heavy skid and the numeral 2 indicates a multiplicity of transverse timbers placed side by side upon the timbers 1 to form the top of said skid. A. row of nutequipped bolts 3 connect the outer longitudinal edge portion of each outer timber 1 to the overlying portions of the timbers 2 and double rows of nut-equipped bolts l connect the inner longitudinal edge portions of said timbers 1 with said timbers 2. Rivets 5 conneet the intermediate timbers 1 to the time bers 2. Y

The lower longitudinal edges of the skid are rounded and the entire Vbottom thereof, as well as its rounded corner, is covered with a face plate 6, secured in position by the bolts 3 and l and rivets 5. The heads of the rivets 3 and i and the lower ends of the rivets 5 are countersunk in the face plate 6.

v,As best shown in Fig. V3, the face plate 5 is made up of a plurality of metal sheets, the abutting ends of which are overlapped and connected by the bolts 3 and l and rivets 5.

Extending the full length of the skid, is a pair of longitudinally spaced guide beams or rails 7, formed from heavy timbers and rigidly secured in position by the bolts 4f which are extended therethrough. A metal tread plate 8 rests upon the timbers 2, between the guide rails 7, and is rigidly secured in position by the rivets 5, the upper ends of which are countersunk therein. rlhe ends of the timbers 1 are bent or turned upward in front of the timbers 2 and guide rails to form a runner-like front end for the skid.

A horizontal guard angle bar 9 is secured to each guide rail 7. The horizontal flanges of these guards 9 are turned outward upon the upper faces of said guide rails and their vertical flanges extend downward over the inner faces thereof and terminate above the tread plate 8. These guards 9 are also secured in position by the bolts l, which extend through the horizontal flanges thereof. By forming the tread plate and guards in' dependently, the bottom of the channel of the track is perfectly flat with no rounded corners, as would be if the parts were formed integral, thereby affording a flat surface the full width of the channel, for the wheels of a machine to travel on.

At the front and rear ends of the skid, are wheel stops 10 and 11, respectively, and at the intermediate portion thereof, is a wheel stop 12. All of these wheel stops 10, 11 and 12 are located within the channel of the wheel track and extend across the tread plate 8.

In the drawings, is illustrated a portion of a ditching machine 13 supported on two pairs of front wheels 14 and a single pair of rear wheels 15. The wheels 14 and 15, on one side of the machine 13, are arranged to run on one of the improved wheel tracks. The front wheels 14 are arranged to run between the wheel stops 11 and 12 and the rear wheel 15 is arranged to run between the wheel stops 10 and 12. It will thus be seen that the improved wheel tracks are arranged to draw the ditching machine backward Vin advance of the work.

In beginning work, the ditching machine rests upon the rear end portions of a pair of the improved wheel tracks. As the work progresses, the machine will be moved backward on the wheel tracks, until its rear wheels 15 and rear pair of front wheels 14 engage the stops 10 and 12, respectively. The machine is then jacked up, by any suitable means, a distance sufficient to remove its weight from the wheel tracks. The wheel tracks are now skidded or moved away from the work, until stopped by the engagement of its rear wheels 15 and its front pair of wheels 14 with the stops 12 and 11, respectively. The machine is then lowered onto the wheel tracks and the previous described operation repeated, until the work is completed.

What I claim is:

1. A portable wheel track comprising longitudinally and transverse timbers secured together to form a skid having a run'- ner-like front end, a pair of laterally spaced guide rails secured to the top of the skid, and a tread plate secured to the skid between the guide rails.

2. A portable wheel track comprising longitudinally and transverse timbers secured together to form a skid having a runner-like front end, a pair of laterally spaced guide rails secured to the top of the skid, a tread plate secured to the skid between the guide rails, and a face plate secured to the bottom of the skid.

' 3. A portable Wheel track comprising longitudinally and transverse timbers secured together to form a skid having a run- Uopies of this patent may be obtained for ner-like front end, a pair of laterally spaced guide rails secured to the top of the skid, a tread plate secured to the skid between the guide rails, and a wheel stop extending across the tread plate.

4f. A portable wheel track comprising longitudinally and transverse timbers secured together to form a skid having a runner-like front end, a pair of laterally spaced guide rails secured to the top of the skid, a tread plate secured to the skid between the guide rails, and a pair of guard angles having their horizontal flanges secured to the upper faces of the guide rails and having their vertical flanges turned downward over the inner faces thereof.

5. A portable wheel track comprising longitudinally and transverse timbers secured together to forni a skid having a runner-like front end, a pair of' laterally spaced guide rails secured to the top of the skid, a tread plate secured to the skid between the guide rails, a face plate secured to the bottom of the skid, a pair of guard angles having their horizontal flanges secured to the upper faces of the guide rails and having their vertical flanges turned downward over the inner faces thereof, and a wheel stop extending across the tread plate.

In testimony whereof I affix my signature in presence of two witnesses. Y

DELL BELANGER.
